The man fell Tuesday morning after tripping over an obstruction in the middle of Woodland Avenue on the 6500 block, police told NBC10. After he was hit by the car, the driver stayed on the scene and was not charged.

A photo taken by NBC10’s Matt DeLucia shows a large bulge in the middle of 65th Street. A spokesperson with the streets department told NBC10 that the bulge is the result of “asphalt shoving,” which is caused by the accelerating and decelerating of trucks or buses on the road.

It’s unknown at this time whether it was the bulge that caused the man to trip. Officials continue to investigate.
